Claude already creates multiple agents for some projects just to keep context windows smaller. I don't think it'll be long before they offer a testing agent along with their planning agent.
I prefer having codex author plans and implement, and claude play reviwer. I do swap them from time to time and i have a lot of respect for claude 4.6 and 4.7 but for my domain I think codex does a better job with the authoring.
